There’s some misinformation in the listing here. The Showtown was open through at least 1984. The last film I remember seeing there was Breakin' 2: Electric Boogaloo. Also, if you look at the ads featured on this page in the photos, one of them features the films Vice Squad and Pranks, both of which were released in 1982.

My earliest memory of going to the Showtown was 1977- saw Cinderella 2000.I had a friend at the time named Jay…his sister was married to the manager and I remember he had done some editing to the movie because he was afraid it was too dirty and he’d get busted.
In the early 80’s they had a showing of that old chestnut-‘Poor White Trash’ on a double feature with ‘Poor White Trash 2’,I think…using the same ad campaign I had been seein since I was a little kid!–‘due to the controversial nature of the film…uniformed police will be on hand to supervise admissions’.Well there were no police,but there was a line about a mile long!They packed the joint!
